and useful Improvements in Beadstapling Machines, of which the following is a specifieation'..:'

Thisim'ention 'relates'to a machine for use instapling'or joining together articles joined to form a ring"which is placed inan edge ofa tire casing.

It has be'en formerly the practice to unite the two ends of-the bead strip with an external wra'pping fabric, but this method has prove'nsomewhat unsatisfactory as the bead ends may separate slightly in handling, "making them inaccurate in length. The object' ofthe present invention is to construct a. machine for the purpose of quickly and efficiently uniting the bead ends, which is done by a metallic staple. the ends being forced into close abutting relation just prior tothe stapling operation so that the circular head is of exact dimensions.

The .-st'apling machine is intended to be used and is shown in cmiiliination with a cemrnting anddrying apparatus; the said comhilmtion being .the subject matter of parentapplication No. 312.474. filed J My 22. 19l9,'of whirhthis application is'a division.

i-Lfnrther ohject of this im'cntion is to construct a machine which will quickly and ellicicntly staple the beads and'clinrh the staples under the head which insures a tight juintat the rnds of the head.

These and other ohjcrts will l t' apparent as the description print-reds. and from an i spection of the drawings accompanying this appliration. it will he undrrstooi'l that the form of marhiuo shown in the drawings is illustrative of the iuycution nwrrly am lithe invention i -f liqtflidllllttl liti llltl p'l'ci isc ilc-"p I pan-land serves to disconnect the two parts.

The apparatus as'shown in Fig. 1 com- F ig. 3 is'a. front'elevation of the-staplingprises a stapling machine unit, a coating or dipping =appa ratus,=and a drying rack. The stapling machine 18 shown at A, the coating or dipping apparatus at B and the drying rack at C.

The stapl ng machine comprises a frame-- work '1 which supports 'a platform 2 and a table 3. To the front of the framework is attached a trough or rack 4 in which are laid the semi-cured heads cut to the proper length. the forward end of the trough being bent or curved upwardly as at 5.

At one side of the machine is carried a platform 6 on whi h is supported the motor T for driving-the machine by means of-a pinion 8 in mesh with a main driving gear 2). The last mentioned gear is secured to a. shaft 10, rotatahl \-"monnted in a bracket 11. carried on the platform 2. On the opposite enchthe shaft 10 carries a pinion 12 in mesh with a gear 13 on the driving shaft H. On the opposite end of the shaft 14 is secured a disk 15. which constitutes one unit of a single revolution clutch. the other portion being the surrounding annulus 16. The part 15 is provided with a notch 17, and the part 16 with a pawl 18 which are designed to lock the clutch for driving hich the clutch is operated. A spring: 24 normally holds the lever t9 in position to disengage the clutch.

From the portion 'ltwof the cluttrhais driven a sprocket chain 26 which passes around a s'pttttltttfli on a shaft 28 which extends across the niitcltineaud iuayfh c termed the main cam shaftf' i V On the tahle 3 is carried the staplingnta chine head which comprises a hasWpttrti'dh 29 and an o verhaaging. head .30. of the base portion of the is provided with a vertical guidcway 1H in which is'arranged for reeiprra'at-ion the head carrier itiL-a set screw limit the downward movement of the carrier. which earricr is;.s hown detached in Fig. In ;the"eentct;,.o'fithe upper surface.

therefrom is arranged a slot or groove 33%. the purpose ofi which.will,presently.appear.

At the sides of the support are arraiigred dove tailed rihsxjir guides 34.. on which are mounted for longitudinal reciprocation a pair of sadidles 35, tl te -.upp'er surfaces of whiehjare formed-with gmovesjltlto receive ill lll'id 1: 2

To each of theisaddlcs,- 5 is pivoteda link 38. which islpiroted totansjartn 39.;seeured to a rocking: shaft 4.0. Lllrom theverticalmovable bead-carrienfiiate extended at zboth sidcs'lugs or cars 41 which form hearings for the rocking! shaft. r i v To the front end of oneof the shafts 40 is secured a lever-42. the free. end of which is formed with 'a forked'end 43g tlie other shaft carrying a lever 44.. the end of which. is jointed h. v a pin lltnvith a vertical rod 46.

The forked end-of the lever 42 passes over,

the pin in order that the two arms may he melted in unison.- On each reciprocating saddle is carried a'pin 47 which is arranged to enfgage with a stop 48 projeetingfrom a plate secured to the front of the head carrier.

It will he understood that the head length is taken ruin the trough or rack 4 and heataround to form a circle. the ends heing abutted an'd placed-on the support 33. .The head carrier is then raised to hring the bead in position to he stapled and at the'salne time the saddles 535 are moved inwardly slightly on the guideway 34. due to the fact that the pin 45 is stationary and the npward -movement of the carrier is translated into an inward movement of the saddles as will he readily understood. which inward movement serves to push the ends of the head together.

'ln-n the staple has heen driven into the head. it is necessary to clinch the ends. it is impractical to rel v upon the surface. (ff

These anvils take the form of tongues 47' extended from 'tlie sadilles aiul arranged to reriprm'ate in the, 'roove ,33 in .the support. The forward .eud of each, tongue or slide-l? is fort'ned with a semi-rirrula r recess 48 or 48" which, when the carrier is raisc his located under 'tln-- poin t;-where tlustaple iierccs the head.

A cover strip 94 is placed over a portion of the lower end of the rail and pre' vents the staples from falling off the rail at this point. i

This 'action is partially carried out by the movement inward 'of'Ethe'saddle 35 as the head carrier moves upwardl v. It is furtheninsured by positive gripping means, which are emhodied in claw levers 112 pivoted to the front of the machine. at 113.

A light spring; 117 on each claw lever serves'to hold the roller 11? against the cam on'the slide. It will he seen from an inspection of Fig. 5 that as the hammer starts to descend. the claw teeth grip the head. which has been raised by the carrier, and just before the staple is driven. the ends are squeezed tightly together.
